Trigger TTL Adjustments Not Showing up on Strobe Screen. TTL to ManualUpdated 17 days ago

When using an FJ Wireless trigger, such as the FJ-X3 M (S), FJ-X2 M, or the FJ80 (II and SE) in Host Mode, you can adjust TTL exposure compensation by ±3 stops (±5 stops on Fuji).

Total TTL Exposure Compensation Value

The FJ Wireless system offers a unique feature that allows TTL exposure compensation to be adjusted both on the trigger and on the flash unit itself. These two adjustments are combined to produce a total compensation value.

For example:

• If you set a +3 adjustment on your trigger, your strobe will output 3 stops more power.
• If you then add a +3 adjustment directly on the strobe/flash unit while the +3 on the trigger is still active, the result will be a total adjustment of +6 stops.
  
  
• Please note: When using TTL, the camera and host unit communicate with each other to automatically determine the optimal flash power for the scene. If your TTL photo appears too dark—even with the flash already firing at a high level (e.g., power level 6)—the maximum effective adjustment available may be limited. A +3 compensation might bring the unit to its maximum of power level 9 (full power).
  In cases like this, if you attempt a combined +6 adjustment (e.g., +3 on the trigger and +3 on the flash), the system will only reflect a 3-stop increase in exposure—because the unit cannot exceed full power (level 9 or 1/1).

How to View TTL Exposure Compensation on Your Strobe

Westcott’s TTL to Manual feature allows you to see TTL exposure compensation values from the host unit, along with the actual power output used during the last TTL exposure. This is especially helpful for monitoring power levels, as lower output can lead to faster recycling times.
